A voltammetric investigation of the reactions between surface-confined amines and quinones on gold electrodes: Evidence for imine formation

A surface-confined layer containing naphthoquinone was prepared by reacting 2,3-dichloronaphthoquinone with the amino tail groups of an aminoethanethiolate-modified vapor-deposited gold surface; this surface layer was then reacted with beta-ferrocenylethylamine. These modified gold electrodes were examined with cyclic staircase voltammetry in aqueous HClO4 at the completion of each step in this sequence of reactions. The voltammetric signature for the 2e-, 2H+ reduction of the quinoid redox centers disappeared after the ferrocene compound was reacted with the naphthoquinone surface layer; furthermore, the surface coverage of ferrocene was twice that expected on the basis of a 1:1 reaction between the surface-bound naphthoquinone and beta-ferrocenylethylamine. These results suggest that the latter reacts with the naphthoquinone carbonyl groups to form a surface-confined di-imine, which cannot be reduced within the electrochemical potential window of aqueous HClO4. In similar experiments, 2-[4?-(beta-ferrocenylethylaminocarbonyl)phenyl]-1,4-naphthoquinone and 2-[2?-(beta-ferrocenylethylaminocarbonyl)-ethyl]anthraquinone were synthesized and reacted with aminoethanethiolate-modified gold surfaces. When examined at a platinum electrode in nonaqueous solvents, both of the freely diffusing compounds exhibited two pairs of voltammetric waves characteristic of quinoid and ferrocene functionalities. However, only the ferrocene redox centers of the resulting surface-confined layers were electroactive, suggesting that the reaction of these compounds with the surface-confined aminoethanethiolate involves conversion of the quinoid carbonyls to imines.

Integrated multienzyme electrochemical biosensors for monitoring malolactic fermentation in wines

Integrated amperometric biosensors for the determination of l-malic and l-lactic acids were developed by coimmobilization of the enzymes l-malate dehydrogenase (MDH) and diaphorase (DP), or l-lactate oxidase (LOX) and horseradish peroxidase (HRP), respectively, together with the redox mediator tetrathiafulvalene (TTF), on a 3-mercaptopropionic acid (MPA) self-assembled monolayer (SAM)-modified gold electrode by using a dialysis membrane. The electrochemical oxidation of TTF at +100 mV (vs. Ag/AgCl), and the reduction of TTF+ at -50 mV were used for the monitoring of the enzyme reactions involved in l-malic and l-lactic acid determinations, respectively. Experimental variables concerning the biosensors composition and the detection conditions were optimized for each biosensor. Good relative standard deviation values were obtained in both cases for the measurements carried out with the same biosensor, with no need of cleaning or pretreatment of the bioelectrodes surface, and with different biosensors constructed in the same manner. After 7 days of continuous use, the MDH/DP biosensor still exhibited 90% of the original sensitivity, while the LOX/HRP biosensor yielded a 91% of the original response after 5 days. Calibration graphs for l-malic and l-lactic were obtained with linear ranges of 5.2 ¡Á 10-7 to 2.0 ¡Á 10-5 and 4.2 ¡Á 10-7 to 2.0 ¡Á 10-5 M, respectively. The calculated detection limits were 5.2 ¡Á 10-7 and 4.2 ¡Á 10-7 M, respectively. The biosensors exhibited a high selectivity with no significant interferences. They were applied to monitor malolactic fermentation (MLF) induced by inoculation of Lactobacillus plantarum CECT 748T into a synthetic wine. Samples collected during MLF were assayed for l-malic and l-lactic acids, and the results obtained with the biosensors exhibited a very good correlation when plotted against those obtained by using commercial enzymatic kits.

Recent developments in design and functionalization of micro- and nanostructural environmentally-sensitive hydrogels based on N-isopropylacrylamide

Synthesis of environmentally-sensitive, and therefore smart hydrogels of micro- and nanosize allowed substantial shortening of time of response of these gels to a change in environmental conditions. This made the hydrogels much more attractive and opened new possibilities of their applications. In this paper we present recent developments in ways of construction of micro- and nanogels, their adaptation to particular needs and possibilities of use. The focus was given to individual, spherical particles and very thin layers of gels on solid supports, including electrodes.

Effective Recognition of Different Types of Amino Groups: From Aminobenzenesulfonamides to Amino-(N-alkyl)benzenesulfonamides via Iridium-Catalyzed N-Alkylation with Alcohols

(Chemical Equation Presented). A simple, highly efficient, and general strategy for the direct synthesis of amino-(N-alkyl)benzenesulfonamides has been accomplished via direct N-alkylation of aminobenzenesulfonamides bearing both different types of amino groups with alcohols as alkylating agents. Notably, this research exhibited the potential for the recognition of different types of amino groups in the N-alkylation of complex molecules with alcohols, facilitating the progress of the transition-metal-catalyzed “hydrogen autotransfer (or hydrogen-borrowing) process.”

Screen-printed carbon electrode modified on its surface with amorphous carbon nitride thin film: Electrochemical and morphological study

The surface of a screen-printed carbon electrode (SPCE) was modified by using amorphous carbon nitride (a-CNx) thin film deposited by reactive magnetron sputtering. Scanning electron microscopy and photoelectron spectroscopy measurements were used to characterise respectively the morphology and the chemical structure of the a-CNx modified electrodes. The incorporation of nitrogen in the amorphous carbon network was demonstrated by X ray photoelectron spectroscopy. The a-CNx layers were deposited on both carbon screen-printed electrode (SPCE) and silicon (Si) substrates. A comparative study showed that the nature of substrate, i.e. SPCE and Si, has a significant effect on both the surface morphology of deposited a-CNx film and their electrochemical properties. The improvement of the electrochemical reactivity of SPCE after a-CNx film deposition was highlighted both by comparing the shapes of voltammograms and calculating the apparent heterogeneous electron transfer rate constant.

Multiscale electrochemical analysis of the corrosion control of bronze in simulated acid rain by horse-chestnut (Aesculus hippocastanum L.) extract as green inhibitor

Horse-chestnut ethanolic extract was tested as potential corrosion inhibitor of bronze in simulated acid rain. The extract was analysed by FTIR, GC?MS and HPLC-PDA, and its anti-corrosion behaviour studied using a multiscale electrochemical approach by polarization curves, EIS and scanning electrochemical microscopy, along with SEM-EDS. 94 % inhibition efficiency was attained by developing a surface physisorbed film. A novel methodology for kinetic evaluation of dynamic adsorption of inhibitive species on metal surface is proposed using SECM, achieving good agreement with results from conventional electrochemical techniques. Excellent adsorption-desorption kinetic constants (ka = 0.102 s?1 mol?1 L; kd = 3.33 ¡Á 10-5 s?1) were determined.
